Deciphering the frontostriatal circuitry through the fiber dissection technique: direct structural evidence on the morphology and axonal connectivity of the fronto-caudate tract.
The authors sought to investigate the very existence and map the topography, morphology, and axonal connectivity of a thus far ill-defined subcortical pathway known as the fronto-caudate tract (FCT) since there is a paucity of direct structural evidence regarding this pathway in the relevant literature. ⋯ By using the fiber microdissection technique, the authors provide sound structural evidence on the topography, morphology, and connectional anatomy of the FCT as a distinct part of a wider frontostriatal circuitry. The findings are in line with the tract's putative functional implications in high-order motor and behavioral processes and can potentially inform current surgical practice in the fields of neuro-oncology and functional neurosurgery.

Neuropsychological assessments before and after awake surgery for incidental low-grade gliomas.
Early surgery in presumed asymptomatic patients with incidental low-grade glioma (ILGG) has been suggested to improve maximal resection rates and overall survival. However, no study has reported on the impact of such preventive treatment on cognitive functioning. The aim of this study was to investigate neuropsychological outcomes in patients with ILGG who underwent preventive surgery. ⋯ Early surgical treatment in presumed asymptomatic patients with ILGG was associated with stable or improved neuropsychological outcomes in 87.2% of patients at 3 months, with only mild cognitive decline observed in 6 patients. In return, supratotal or total resections were achieved in most patients, and all patients were still alive at the end of the follow-up.

Gender diversity in United States neurosurgery training programs.
Neurosurgery continues to be one of the medical specialties with the lowest representation of females in both the resident and faculty workforce. Currently, there are limited available data on the gender distribution of faculty and residents in Accreditation Council for Graduate Medical Education (ACGME)-accredited neurosurgery training programs. This information is critical to accurately measure the results of any effort to improve both the recruitment and retention of women in neurosurgery. The objective of the current study was to define the current gender distribution of faculty and residents in ACGME-accredited neurosurgery training programs. ⋯ This study serves to provide a current snapshot of gender diversity in ACGME-accredited neurosurgery training programs. While there are still fewer female neurosurgeons achieving positions of higher academic rank and serving in leadership positions than male neurosurgeons, the authors' findings suggest that this is likely due to the small number of women in the neurosurgical field who are the farthest away from residency graduation and serves to highlight the significant progress that has been made toward achieving greater gender diversity in the neurosurgical workforce.

Meralgia paresthetica treated by injection, decompression, and neurectomy: a systematic review and meta-analysis of pain and operative outcomes.
Meralgia paresthetica is caused by entrapment of the lateral femoral cutaneous nerve (LFCN) and often presents with pain. Multiple treatment options targeting the LFCN can be pursued to treat the pain should conservative measures fail, with the most common options being injection, neurolysis, and neurectomy. However, their efficacy in causing pain relief and their clinical outcomes have yet to be directly compared. The aim of this study was to interrogate the contemporary literature and quantitatively define how these options compare. ⋯ There are multiple treatment options to target pain in meralgia paresthetica. The incidence of complete pain relief appears to be the greatest among the 3 interventions after neurectomy, accompanied by the lowest incidence of revision procedures. These findings should help inform patient preference and expectations. Greater exploration of the anatomical rationale for incomplete pain relief after surgical intervention will assist in optimizing further surgical treatment for meralgia paresthetica.

Resident evaluations in the age of competency-based medical education: faculty perspectives on minimizing burdens.
Competency-based medical education (CBME), an outcomes-based approach to medical education, continues to be implemented across many postgraduate medical education programs worldwide, including a recent introduction into Canadian neurosurgical training programs (July 2019). The success of this educational paradigm shift requires frequent faculty observation and evaluation of residents performing defined tasks of the specialty. A main challenge involves providing residents with frequent performance evaluations and feedback that are feasible for faculty to complete. This study aims to define what is currently happening and what changes are needed to make CBME successful for the certification of neurosurgeons' competence. ⋯ To facilitate the successful implementation of CBME into a neurosurgical training curriculum, resident EPA assessment forms should take 3 minutes or less to complete and be accessible through a mobile application.
